The global manufacturer of instrumentation valves and fittings, HAM-LET, has launched PuRight™, a newly enhanced stainless steel 316L material.
It offers lower inclusion content, low carbon content for enhanced welding, low sulfur content for enhanced electro-polishing and better corrosion resistance achieved by modification of key elements like chromium (Cr), Molybdenum (Mo) and Nickel (Ni). It was specifically designed to achieve optimum surface quality after certain processes like mechanical or electro-polishing. It is compatible with the SEMI-F20 standard, ASTM-A276 and ASTM-A479/ASME SA479.
The new material is also pitting and crevice corrosion-resistance, which will make it beneficial for applications within the semiconductor industry where corrosive materials are utilized.
“This uniquely-designed alloy has a clear advantage in use for pressure or flow control devices, such as valves, fittings etc. With its excellent welding characteristics and meaningfully-high values of CPT, as well as high ratios of Cr/Fe and CrOx/FeOx, PuRight™ material should prove highly attractive to manufacturers of Ultra High Purity (UHP) products and is particularly well suited for use in the semiconductor industry,” said Felix Shestatski, VP Quality, Engineering and R&D.
